Demand was high for Christmas trees, lights and decorations, along with gifts and festive plants, such as poinsettias.
Website sales rose by 22 per cent in the five weeks to 3 January with children's board games and food hampers proving popular with online shoppers.
Dobbies – which was taken over by Tesco in 2008 following a battle with rival shareholder West Coast Capital, owned by entrepreneur Sir Tom Hunter – has 25 stores, including 13 in Scotland.
Chief executive James Barnes said: "Our customers made a return to a much more traditional Christmas with our biggest sellers being real trees, poinsettias, wreaths and traditional accessories such as cinnamon-scented pine cones."
Dobbies restaurants – which account for more than 20 per cent of the total business – grew like-for-like sales by 3.5 per cent, while revenue at the company's "farm food halls" rose by 2.8 per cent.
Barnes – who joined the company in 1989 as development director and who led a management buyout in 1994 – said the performance of the food halls and restaurants was driven by the success of the firm's home baking.
The company traces its roots back to 1865 when James Dobbie – chief constable of Renfrew – began selling seeds from his home-grown giant leek.
On Monday, rival chain Garden Centre Group described Christmas trading as "terrific" after ditching its Wyevale branding.
